Mosto.Ai - All AI in One: Claude, ChatGPT, Gemini & Grok Sidebar

Mosto.Ai is a smart assistant that lives in your side panel and opens on any page. Several leading models in a single window: pick the right one for the task and never lose context. ▍AI aggregator A single panel instead of a dozen tabs and separate accounts. GPT, Claude, Gemini and Grok sit side by side: ask a model, switch to another and compare answers. Mosto.Ai brings top language models into a single interface, so you spend time on work, not on hunting for the right service. ▍All AI models in one place Writing an email, reviewing a document, learning a language or drafting a post - the right tool is always at hand. Single sign-in, shared chat history, the same clean interface for every model. ▍AI for answering questions Ask anything: explain a hard topic in plain words, solve a problem, suggest a formula, plan a trip. You get clear, detailed answers and can keep asking follow-ups in the same thread. Great for study, work and everyday life. ▍Translate and summarize Long article in another language? Ask for a translation or a few-bullet summary. The result appears in the panel next to the source - no copying, no switching windows. ▍AI in your browser Mosto.Ai works on top of any open page. Ask about the site's content, get an unclear paragraph explained, or pull out the key points of a long read. The assistant sees the context and answers about what is in front of you. ▍Sidebar extension Open the side panel with a click or a hotkey; it never covers your main tab. Read, scroll and chat at the same time - the panel stays put while you move between sites.
